This article tells of a new strain of HIV,.located in Saskatchewan, Canada. For now, it seems to be geographically specific. I'd imagine many strains develop like this. A constant exposure to the elements & factors specific to a given region allow for new adaptations. This doesn't mean the virus will remain limited to this region. As people travel, so will the virus.
This new strain is being mostly found in the marginalized people's of this area. It is being transferred mostly via shared needles. This outbreak is being fulled by poverty, marginalization & drug use. People with this strain are progressing to AIDS sooner & are having higher mortality rates. This is a scary, but expected development.
